Do Hot Water Solar Panels Create Ac Or Dc

Well not quite the first issue is the hot water heater s thermostat contacts are designed to handle ac loads only so we have to use a contactor ssr to switch the solar panels in and out.

Do hot water solar panels create ac or dc.

The electricity generated from solar panels is in the form of dc or direct current. Such a system can also be designed for an ac motor of different power ratings which is available in the. An inverter is an electronic device that produces ac power as its output whenever dc power is provided at its input. The price of a suitable solar hot water system is about 4 000 installed.

A device called an inverter is required to convert the dc electricity from solar panels into appliance friendly ac. Direct current dc electricity is what solar panels produce and what batteries hold in storage while alternating current ac electricity is the type used on the grid and in most household devices. A couple of my thoughts. The design of such a system is very simple as we have to match the power and voltage rating of the pv module to that of the dc pump motor so when the module receives the solar radiation the pump will draw the water and store it in the tank.

Good work and when the hot water gets too hot which probably never happens you have a thermostat and relay to disconnect the solar modules. That s for a flat plate thermosiphon tank on roof style system like the one in the first pic above. The inverter by itself does not generate any power.

Problem is high voltage dc solid state relays are rare and if they do exists they cost a lot. Use a solar hot water system to heat the water directly. If you are using an ac thermostat and you are putting dc through it to trigger the relay expect the thermostat to wear out prematurely catch fire or have the contacts of the thermostat weld together.
